Self-confidence is the most attractive quality a person can have. How can anyone see how awesome you are if you can't see it yourself.
You face problems at work or at home and you hear a voice in your head that it can't be done, or that you aren't good enough. What voice do you think this is? It is your ego isn't it? Your narrow and restricted vision of yourself. It is ok to hear this voice but it isn't ok to be disheartened by it. Have you ever seen the face of someone who is determined to succeed? Walls crumble under this will-power. Be inspired by these people and repeat their feat. As they say, "feel the fear and do it anyway!"
You are a miracle worker when you sign up for a spiritual path. So let whatever problems and challenges that you may face come into your life without resisting them. They make you great. They show you that the sky is the limit. In fact, it is your obstacles that help you discover the Voice of God. Learn how to step across the restrictions of the little I. Self empowerment is spirituality. Know who you are and let the world know about it.
